The U.S. Army Corps of Engineers and its non-Federal sponsors SJAFCA and the State of California Central Valley Flood Protection Board, propose to improve flood risk management in North and Central Stockton by repairing and enhancing the levees that surround the city, and by construction and operating closure structurs on Fourteenmile Slough and Smith Canal. The project would combine the levee improvement measures of cutoff wall, deep soil mixing, and levee geometry improvements, and would address projected sea level change by including raising the levee height where needed. There would be an additional levee extension on Duck Creek to prevent flanking.
